how to check used tranny
 

Hi everybody, i bought a used SI tranny from a guy who was working in Defcon Racing last July. I finished all parts collection and finished the auto to manual conversion yesterday. However, after i started the car up, the tranny was running noisey even in neutral. Noise gone after I press clutch. So it should be bad bearings in tranny then.... :(

I'm debating if i should rebuild the tranny or go for another used one. If I go for another used one, how can i know if the tranny is good? Some sellers may not tell me the truth. Please help, i feel tired to take off the tranny again.

Did you change the throwout bearing?

I did, i installed brand new OEM clutch pkg with throwout bearing. if the problem is from throwout bearing, the noise should be even louder when i press clutch.

input shaft i think

:dito: thats my guess input shaft bearing

Input bearing, had the same problem

noise is there press the cluch its gone, and when your driving its gone right,

drove around for about 3-4 months like that now my input and realse is gone,

althought the input bearing is about $30 check with Cadsii or however you spell his nick he has a write up of how to change it, he just did the Motor, DYI motor build up

here is the step by step writeup with pictures :)

Thank you very much guys. I'll bring it to Mister Transmission for quote coz I cannot afford long downtime. i really hope it's all becoz of input bearing, not the bearings on countershaft too...

if you have a d series engine. it would be cheaper to get another tranny... but then i suppose you could end up in the same spot...

on my old dx tranny i was rockin for a bit the input shaft bearing disintigrated and all the tranny fluid covered the clutch and flywheel and oozed out :p

true mr tranny wants 380$ just to swap a tranny for another one hA!! rip off

I'll check how much they want tomorrow. if it's under $200, i'll let it go. otherwise, u guys ar correct. I should take another tranny. But again, how can u tell if the used tranny is good.

problem found. it's becoz of bad ISB. I'm gonna call Defcon Racing for parts money. Becareful to buy anything from them, or the guy called SixPak on clubsi.com
